Javalin
Javalin
You never extend classes and you rarely implement interfaces. Javalin is just a few thousand lines of code on top of Jetty, and its performance is equivalent to raw Jetty code. Due to its size, it's very easy to reason about the source code. Other Java and Kotlin web frameworks usually offer one version for each language. Javalin is being made with inter-operability in mind, apps are built the same way in both Java and Kotlin. Javalin runs on top of Jetty, one of the most used and stable web servers on the JVM. You can configure the Jetty server fully, including SSL and HTTP3 and everything else that Jetty offers. Many lightweight Java and Kotlin web frameworks don't support OpenAPI, but Javalin does. -

Preact
Preact
Preact provides the thinnest possible Virtual DOM abstraction on top of the DOM. It builds on stable platform features, registers real event handlers and plays nicely with other libraries. Most UI frameworks are large enough to be the majority of an app's JavaScript size. Preact is different: it's small enough that your code is the largest part of your application. That means less JavaScript to download, parse and execute - leaving more time for your code, so you can build an experience you define without fighting to keep a framework under control. Preact is fast, and not just because of its size. It's one of the fastest Virtual DOM libraries out there, thanks to a simple and predictable diff implementation. We automatically batch updates and tune Preact to the extreme when it comes to performance. We work closely with browser engineers to get the maximum performance possible out of Preact.Starting Price: Free -

Growler
Growler
Growler is a web framework built atop asyncio, the asynchronous library described in PEP 3156 and added to the standard library in python 3.4. It takes a cue from the Connect & Express frameworks in the nodejs ecosystem, using a single application object and series of middleware to process HTTP requests. The custom chain of middleware provides an easy way to implement complex applications. The pip utility allows packages to provide optional requirements, so features may be installed only upon request. This meshes well with the minimal nature of the Growler project: don't install anything the user doesn't need. That being said, there are (will be) community packages that are blessed by the growler developers (after ensuring they work as expected and are well tested with each version of growler) that will be available as extras directly from the growler package. -

Tornado is a Python web framework and asynchronous networking library, originally developed at FriendFeed. By using non-blocking network I/O, Tornado can scale to tens of thousands of open connections, making it ideal for long polling, WebSockets, and other applications that require a long-lived connection to each user. Tornado is different from most Python web frameworks. It is not based on WSGI, and it is typically run with only one thread per process. While some support of WSGI is available in the tornado.wsgi module, it is not a focus of development and most applications should be written to use Tornado’s own interfaces (such as tornado.web) directly instead of using WSGI. In general, Tornado code is not thread-safe. Tornado is integrated with the standard library asyncio module and shares the same event loop (by default since Tornado 5.0). In general, libraries designed for use with asyncio can be mixed freely with Tornado. -

The web platform has what you need and never goes out of fashion. Ditch throbbers and loading screens by removing framework bloat and authoring only the code you need. When you learn Enhance, you’re learning development approaches that will last as long as the web does. Enhance apps are designed with deployment in mind. When you're ready to launch, we've got you covered with Begin. -

hug
hug
Drastically simplify API development over multiple interfaces. With hug, design and develop your API once, then expose it however your clients need to consume it. Be it locally, over HTTP, or through the command line - hug is the fastest and most modern way to create APIs on Python3. hug has been built from the ground up with performance in mind. It is built to consume resources only when necessary and is then compiled with Cython to achieve amazing performance. As a result, hug consistently benchmarks as one of the fastest Python frameworks and without question takes the crown as the fastest high-level framework for Python 3. hug makes it easy to expose multiple versions of your API. With hug you can simply specify what version or range of versions an endpoint supports and then automatically have that enforced and communicated to your API's users. -

Svelte
Svelte
Svelte is a radical new approach to building user interfaces. Whereas traditional frameworks like React and Vue do the bulk of their work in the browser, Svelte shifts that work into a compile step that happens when you build your app. Instead of using techniques like virtual DOM diffing, Svelte writes code that surgically updates the DOM when the state of your app changes. We're proud that Svelte was recently voted the most loved web framework with the most satisfied developers in a pair of industry surveys. We think you'll love it too. Read the introductory blog post to learn more. Svelte is a tool for building fast web applications. It is similar to JavaScript frameworks such as React and Vue, which share a goal of making it easy to build slick interactive user interfaces. But there's a crucial difference: Svelte converts your app into ideal JavaScript at build time, rather than interpreting your application code at run time.Starting Price: Free -

Sinatra
Sinatra
Sinatra includes a number of built-in settings that control whether certain features are enabled. Settings are application-level variables that are modified using one of the set, enable, or disable methods and are available within the request context via the settings object. Applications are free to set custom settings as well as the default, built-in settings provided by the framework. In its simplest form, the set method takes a setting name and value and creates an attribute on the application. Extensions provide helper or class methods for Sinatra applications. These methods are customarily listed and described on extensions home pages. Using an extension is usually as simple as installing a gem or library and requiring a file. -

SurveyJS
SurveyJS
SurveyJS is a product family of four open-source JavaScript libraries that provide you with all the advantages of a custom-built in-house survey application while significantly reducing time-to-market and resources required to get the system up and running. The libraries are compatible with most popular JavaScript frameworks and can communicate with any server that can post and get a request in JSON format, which makes them server- and database-agnostic. The product family is composed of: > An open-source MIT-licensed rendering library that renders dynamic JSON-based forms in your web application, and collects responses. > An self-hosted drag-and-drop form builder that features an integrated CSS-based theme editor and a GUI for conditional rules. > PDF Generator, a library that renders SurveyJS surveys and forms as PDF files in a browser. > The Dashboard library that allows you to simplify survey data analysis with interactive and customizable charts and tables.Starting Price: 499/once -

Blazor
Microsoft
Blazor lets you build interactive web UIs using C# instead of JavaScript. Blazor apps are composed of reusable web UI components implemented using C#, HTML, and CSS. Both client and server code is written in C#, allowing you to share code and libraries. Blazor is a feature of ASP.NET, the popular web development framework that extends the .NET developer platform with tools and libraries for building web apps. Blazor can run your client-side C# code directly in the browser, using WebAssembly. Because it's real .NET running on WebAssembly, you can re-use code and libraries from server-side parts of your application. Alternatively, Blazor can run your client logic on the server. Client UI events are sent back to the server using SignalR - a real-time messaging framework. Once execution completes, the required UI changes are sent to the client and merged into the DOM.Starting Price: Free
